SPECIFICATION forming part of Letters Patent No. 721,920, dated March 3,1903.

\ Application filed eptember 18, 1902. $erial No. 123,853. (No model.)

To aZZ whom, it may concern.-

Be it known that'I, J OSEPH Z. STAFFORD, a citizen of the UnitedStates,residingat Canyon Ferry, in the county of Lewis and Clarke andState of Montana, have invented certain new and useful Improvements inDitching-Plows and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which itappertains to make and use thesame, reference being had to the accompanying drawings, and to thefigures of reference marked thereon, which form a part of thisspecification.

This invention relates to ditching-plows, and is designed to beparticularly used to clean or scrape ditches which have first beenplowed by an ordinary plow.

The object of the invention is to form an improved device of thecharacter stated which will clean several furrows and lift and throw theloose dirt to one side of the ditch.

In the accompanying drawings, Figure 1 is a top plan view of the device.Fig. 2 is aside View thereof. Fig. 3 is afragmentary plan view showingthe construction permitting adjustment of the landside.

Referring specifically t0 the drawings, 6 indicates a beam or blockwhich is beveled and shaped at its front end to form the plow-point,which is covered with a metal plate 6 in case the beam is formed ofwood. An eyebolt 6 permits the attachment of draft-animals. A landside 7is set into the beam behind the point and is hinged thereto by a hinge 7which permits an adjustment of the landside according to the width ofthe ditch. The

braces '7", which extend from the landside over and under the beam, holdthe landside at such adjustment, being fixed by a bolt 7 through thebraces and through one of a series of holes 6 in the beam. These bracesare placed at both top and bottom of the landside "and beam for the sakeof strength, inasmuch as the amount of the earth moved and the pressureare usually considerable. At

the lower edge of the landside is a projecting plate 7 which enters theland beside the f urrow and holds the plow to its work by preventingjumping thereof. The plate is suitably shaped and sharpened to out underthe land.

The moldboard'is indicated at 8 and is of peculiar shape. It is attachedby angle-irons to the side of the beam 6, some distance behind thepoi'nt, and is supported by braces 8.

The lower edge 8 of the moldboard is a cutting edge and extendslaterally, substantially flush with the bottom of the beam. The purposeof this is to out under the furrows made in advance by the ordinary plowand to lift and move the same to give the requisite width to the ditch.From the cutting edge the moldboard curves backwardly and outwardly, asusual, and serves to lift and throw the dirt cleanly to the furrow sideof the ditch, which is ordinarily the lower side.

In operation the block or beam is run in the last furrow. The moldboardtakes under the furrows and lifts and throws the same, and by reason ofthe location and shape of the moldboard a wider ditch can be cleanedthan with those scrapers in which the moldboard is presentedperpendicularly to the earth of the furrows. My plow lifts the dirt outand over to the lower side of the ditch being plowed. It will be founduseful particularly in cleaning ditches and in roadwork.

What I claim as new is- A ditching-plow comprising a beam pointed at itsfront end, a moldboard and a landside attached to the beam between itsfront and rear ends, and braces from the rear end 'of the beam to themoldboard and landside,

the landside and its braces being adjustable with respect to the beam.

In testimony whereof I affix my signature in presence of two witnesses.

JOSEPH Z. STAFFORD.
